With Office 365 tenant restrictions in place, access to the Microsoft Learn Sandbox's Office 365 tenant (used by courses such as https://docs.microsoft.com/en-gb/learn/modules/azure-architecture-fundamentals/exercise-create-website) is blocked:

Message: AADSTS500021: Access to 'Microsoft Learn Sandbox' tenant is denied.

There doesn't seem to be anything in Microsoft's documentation for this and a Google search for Access to 'Microsoft Learn Sandbox' tenant is denied. returns absolutely nothing, hence this post. enter image description here

For now, we've granted access by using the directory ID, 604c1504-c6a3-4080-81aa-b33091104187, from the URL but this isn't ideal as it's not human-readable.

Does anyone know what the tenant's default AAD FQDN (<something>.onmicrosoft.com) is?

I guessed microsoftlearnsandbox.onmicrosoft.com and it does exist according to https://login.microsoftonline.com/microsoftlearnsandbox.onmicrosoft.com/v2.0/.well-known/openid-configuration but it didn't work here.

 

Edit (2022/03/16 15:36): While using the Microsoft Learn Sandbox, I happened across a UPN named <username>@triplecrownlabs.onmicrosoft.com which is in line with what Bobbert said / found.

  • I am the IT administrator. Contacting the Microsoft Learn Sandbox tenant administrators is likely to be very difficult, time-consuming, and unsuccessful so I was hoping that someone would just know. And if they don't and I do manage to find out myself then I'll post the answer here "Q&A style" which is encouraged. Commented Jun 23, 2021 at 11:28
  • Doubt anyone will be able to tell you what the domain name is, since it seems this is not publicly available data. beside, I fail to see the need to have the domain name if you can just use a tenant ID, contact Microsoft directly maybe? Commented Jun 25, 2021 at 8:29

    @Michael Hampton It does seem to be correct as login.microsoftonline.com/triplecrownlabs.onmicrosoft.com/v2.0/… has the exact same Directory ID GUID that we managed to allow access with. I am curious how Bobbert managed to find it, though. Commented Aug 14, 2021 at 23:15
